lo all wlw/1n 'it may concern:

Be it known that I, VAN DON HABLAN, a

citizen of the United States, and a resident of `Humphrey, in the county "of Jefferson and State of Arkansas, lhave invented certain new and useful Improvements-in Cotton-Cleaning Machines, of which thefol-` lowing is a specification.

This invention relates to a cotton cleaning machine.

In all cotton seed received at a cotton oil in'ill there is a considerable amount of good cotton in the form of cotton locks and linters which vhave become mixed with the cotton. seed, hulls, and other `foreign matter present in the seed as delivered to the oil mills. Linters-usuallyaccumulate in a seed house at a gin in the form of flakes, chunks, or balls. These linters are 'of some value but it is necessary that they are separated from the locks of cotton, which are of greater value than linters, for the reason that it is almost impossible to ginthe cotton It is an important object of the invention that the cotton locks reclaimed be entirely free from all foreign matter.

It is also an object of the invention that the machine operate in an efiicient and eX- peditious manner.

Other objects,` and objects relating to details of construction, combination and arrangement of parts, will hereinafter appear in the following detailed description to follow.

The invention is illustrated by Way of eX- ample in the accompanying drawings, in which:

Figure 1` is a view in side elevation of the machine,

Figure 3 machine, y

. Figure 1 is a. transverse sectional View taken substantially on the line 1T-4 of Figure 1,

Figure 5 is a vertical sectional View of the is a front end elevation of the tudinally thereof,

I Figure 6 is a fragmentary View illustrating tliemanner in which the cotton gathering teeth employed are arranged in the sift- -`ing dium, and `Fig-ure 7 is a detail view further illustrating the construction of the cotton gathering -teeth ifand the rings for holding the same wit-hin the sifting' drum;

Referring" to the drawings more particularly the machine may incl-udea housing` generally indicated by the-reference char- -act'er 10.` This housing may be supported by a base 11 and supports 12. `The housing may be substantially square in cross section and -inclined longitudinallyv as best shown in Figure 1. s

ithinthehousing 10l there is vdisposed aid-rum 13, said drum being arranged longitudinally of the' housing as shown and revolubly supported 'by rollers: 14. Each roller`-` 14 may be journaled by suitable VAN. ,non nan-LAN, or nrnurnnnr, AiaxANsas.

brackets `carried by the housing 10. Suit` able bands 15 may be carriedby the drum upon lwhich the rollers may engage, and each band provided with a rib 16 to hold the drum', against" rlhe drinn is perforated, said perfo-rations being"arranged -circumferentially of lthe drum as shown at 17,'Figure 5. Vithin the drum there is positioned a plurality of longitudinal movement toward the lower endof the housing 10.v

bands 18, each band vbeing perforated cir cumfe'rentially as shownV at 18', in Figure 7 and said perforations being soy arranged in each instance that the same will register with a row of perforations 17 in the drinn 13. Between each adjacent pair of bands 18 there is held a cotton gatheringelement 19. Each element 19 is in the form of a ring 2O which has 'its inner periphery formed with teeth 21 extending in a similar direction. Flach` ring QO'niay be in sections to enable easy positioning and removal of same. The outer periphera edge of each ring 21 is provided with securing tangs 22and each tang l 22 may be providedivith a rivet receiving Figure 21s a rear end elevation of the' opening 23. The cotton gathering elements or members may be solidly held withiny the tended through thewdrum 13 and openings or `holes 2310i3 the members 19 to rigidly selcure the saine to the drinn.

`The drum 13 is open at each end and within the drum ad]acent the inner periphery thereof there is positioned a rotat-k the `reference numeral 32.

able` cylinder l .This cylinderhlentends by the end walls of the housing 10. The

cylinder 24 carries brushes 25 which are.

adapted to engage with the teeth 2l`of the cotton gathering elements., Also similarly located within the drum is a second cylinder 26 carryingthe radial teeth 27,.said teeth being arranged in rows circumferentially*0f the cylinder 26. Eachrow of teeth is adapt'- ed to move between a pair of adjacent cotton gathering members 19. The cylinder 26 is rotatably supported by shaft 2 6 and this shaft is suitablyjournaled by the'end walls of housing 10, as best shown in yFigure 5.

The `housing 10 is formedwith a-trough 27 which extends longitudinally thereof, and withinL this-trough there is' disposed a shaft 2 8 carrying spiral form of blade 29. The shaft28 is( also rotatably supported by the end walls ofthe housing 10. The lower end ofthe trough 27 communicates --with a spout 30. f v i It should be here notedthatthe cylinder 26 does not extend the entirelength-ofthe I .f drum 13, viz., this cylinder extends `from the upper end of the drum to a point near the lower end thereof, and the portion of shaft 26, between vthis last named en dof cylinder 26 andlower end .ofdrun'i carries a plurality of radially extending blades 31. The blades are of such width that they will not engage the teeth 21 of thecotton gather ing or collecting members 19.

lfithin the drum longitudinally thereol is supported a frame generally designated b):

the frame and serves to act as a cottonftransfer means between the brushes 25 audth` conveyor belt 34. The conveyor frame 32 also carries a deflectorboard, 37 ,whichv yis equal in length to either of vtheblades 31 carried by the shaft 26. 1

A chute or spout 38 is carried by the lowerinost end wall of the housing 10, said i chute being disposed in receiving 4relationto the associated end of the drum 13.

Above the housing 1() there is rota-tabl) i supported ay shaft 39 which carries apulley 40 at one Vend over which passes abelt1 all operatively connected to the'electric motor 412. y The lforward endA of the conveyor. frank.;l 32 carries a discharge nozzle. 43 which if; preferably hinged as at 454, This discharge This frame is yof the* drum 13l into the .trough 2i'.

is'disposed toadeosit cotton upon :i conveyor 45. The sha t 39 is adapted to drive the conveyor belt 34 through the shaft 4:6, belti and pulleysVlS, and 49.

4Upon one side of the housing 10 there is 'journaled ashaft 50. This shaft is 0pera- Atively connected t0 the shaft 39 through the beltvl and necessary pulleys as shown. A belt 52 passes about thedrum 13 and about a pulley 53 carried by the shaft 50.

The shafts 24- and 26 are operatively connected lto the shaft 50 through the belts 54C and 55 respectively', yand the necessary pulleys as shown. connectedzftro the shaft 28 through the belt 56 and necessary pulleys as shown. ,v

Itl should be noted that the bottom ofthe The shaft 50 is also housing 10 comprises two inclined sections y.; 57. These sectionsterminate at their lower kends `with the side walls of the trough 27.

` Thespout or. chute 33 hasits lower end fin registering relation (to a conveyor 1ndieatedf-at'lS. Also it will be noted that,

the `forward endwall of the housing 10-` is provided Lwith anl opening of relatively large sip/ie. as shownat 60. A

In Autilizing the present machine the grabot cottonl` is thrown through the open-.

ying 60 upontheinner peripheral surface of the drum 13. The drum revolves in the direction of arrow 61 Figure 2. Thecylinder 24. carrying the brushes 25 revolves in the saine direction and the cylinder 26 revolves in the opposite direction tothat of the druni 13v and cylinder 24. Thel conveyor belt 34 nieves in a direction to deliver cotton to the discharge nozzle' 4.3.

4Rotary,movement of the drum 13 carries Vthe uncleaned cotton upward and toward the cylinder 26. T he sinall foreign oarticles in the cotton drop throughthe per orations These particles are carried downward to the spout 3() by the spiral blade or vane 29 carried by shaft 28.

Theteeth 21 of the collectinginembers 19 gather locks of cotton and carry the saine toward" the brushes of cylinder 24. The teeth 27 of cylinder 26 permit these locks of cotton to pass. a The brushes 25 'collect these locks of cotton from the. teeth 21 and throw the saine upon the board 36.

-The locks of cotton gravitate upon the lintersV which are in the form of'balls of cotton,` 'and are valuable.

These linters will accumulate between the collector menibers 19 and upon being brought to the teeth I2i' 'of lcfy'linder 26, thesainewill be thrown to the" bottoni of the drum;v This operation `will continue as these dimers gravltate toward the lower end of the drum 13.h The blades 31 of the shaft 26 will permit the linters to pass, and upon said linters reaching the brushes 25 the same will be of my invention as indicated by the ap` pended claims.
